Create a writer website or blog. A website not only demonstrates your technical ability, but it also creates an online hub that allows clients to connect to you. Keep the design of your website clean and uncluttered. Include examples of your work that demonstrate the kind of writing you do. Make the samples easy to find and to read, and make it easy for visitors to figure out how to contact you..
I’ve made a video about this in the past but basically the reason this works is when you’re sharing out your content through big niche related social accounts they’ll attract a LOT of social reshares and natural links from other websites. And this is exactly the kind of thing that Google likes to see and exactly how I get my sites ranked in the search engines.
